1 Claim.

This invention relates more particularly to window frames of wood.

In such window frames, as heretofore constructed, the sill member has been secured in place by nails driven through the stiles into the opposite ends of the sill and when the carpenter trims off the end of the pulley stile projecting below the sill no support is left for the ends of the sill except the nails. Because of this construction, by the raising and lowering of the bottom sash, the sill is forced down creating an opening at the intersection of the sill and pulley stile through which the water of rain or snow fiows causing rotting of the sill and the stiles.

One object of my invention is to provide a con nection between the sill and stiles whereby tight and accurate fitting can be efiected and maintained so as to avoid the undesirable results stated. This I accomplish by my construction herein described whereby a portion of the wood of the stile is left after trimming to provide ample support for each end of the sill, and further, it will maintain water tight joints. Other objects will appear from the disclosure.

In the accompanying drawing- Figure 1 is a view in elevation, broken out vertically and horizontally, of a window frame according to the invention.

Fig. 2 is a sectional view vertically on the line II-II, Fig. 1, looking to the right.

Fig. 3 is a detail perspective view looking at the right hand end of the sill, as seen in Fig. 1.

In the views 5 designates the stiles,- the pulleys therein being shown at 6.

The lower ends of said stiles at their inner sides are gained as at l and at a slant from the inner side of the frame downward.

The character 8 designates the sill. Said sill is rabbeted at each of its opposite ends to form a tenon 9 so that the sill can be entered at its opposite ends in the gains 1, 1, and be supported by the material of said stiles. The tenons 9 can be painted or coated with paraffin, or a solution thereof, to make the joint tighter.

eling toward the main body of the sill.

The

sill at the outer side has at each of its ends a projection H for exterior trim.

A longitudinal saw kerf I2 is provided at the inner edge of the sill to guide the carpenter in sawing off the portion to finish that edge.

At i3 is the usual casing or trim for the exterior side of the wilndow frame.

From the construction shown and described it will be observed that a tight and permanent fit and support for the ends of the sill are provided and that the construction is adapted to prevent the passage of water to and decay of the contiguous wood below.

invention as claimed. What I claim is:

A window frame including pulley stiles having tenon receiving gains at their inner sides, a one piece sill consisting of a body portion having a tenon projecting from each of its opposite ends in the direction of the length of said body portion, said tenon being of a thickness less than the thickness of said body portion and having the upper surface thereof substantially flush with the adjacent upper surface of said body portion and trim horns at opposite ends of said sill and integral therewith and extending in the direction of the length of the sill beyond the aforesaid tenons, said sill connected with said stiles at said gains by sidewise movement of the stiles onto said tenons in the direction of the length of the sill.
